Protective coatings for titanium-aluminium alloys and carbon-carbon composites have been synthesized and characterized for hypersonic vehicle applications. Coatings of choice must show protection against oxygen and hydrogen under mild environments of low flows and temperatures and under severe environments of high flows and temperatures. Aluminium-silicate glass ceramics were chosen as coating candidates because they are materials that are stable to temperatures of 1500 Cel, are nonreactive to oxygen, and have minimal reactivity with respect to hot hydrogen. This article describes the chemistry of the coating synthesis and application as well as the characterization of such coatings.
